SPRING-ROLLER.

SPECIFICATION forming part of Letters Patent No. 374,060, dated November 29, 1887.

I Application fllcd August 17, 1886. Serial No. 211,168. (No model.)

To aZZ whom it may concern} 7 Be it known that I, EUOHER Games, a citizen of the United States, residing at'Toinbstone, Cochise county, Territory of Arizona, have invented a new Adjustable Solid Spring- Roller for Window-Shades, of which the following is a specification.

My invention relates to the class of springactuated rollers for window-shades wherein a casing secured to the curtain-roller incloses a drum andspiral spring, one end of said spring being attached to the pivot or shaft on which said casing turns, and the other end of the spring being attached to the casing and roller to revolve the same and wind the curtain upon 7 the roller, while the'shaft of the drum is held stationary upon the bracket, a suitable catch being employed to connect the pivot or shaft and casing and lock them together at any required position at which the curtain is to be held upon the roller.

My invention consists in certain constructions and combinations of parts, hereinafter particularly described, and designated'by the claims, with reference to the accompanying drawings, ,wherein' Figure l is a perspective of the rollershade and fixtures complete. Fig. 2 is a perspective of the inner face .of the left-side bracket, and Fig. 3 a similar view of the inner face of the right-side bracket; Fig. 4, a side elevation of the metal end cap and flange to be applied to one end of the roller, and Fig. 5

a similar representation of the end cap and casing for the spring and drum to be secured to the other end of the shade-roller. Fig. 6 is a perspective of the end cap and casing shown in Fig. 5; .Fig. 7, a perspective ofsaid end cap and easing, with thespring and drum, with their connections, inclosed within said casing; Fig; 8, a perspective of the drum, the spring,

and the arbor removed from the casing; and

Fig. 9, a perspective of the key for winding the spring to the required tension.

The brass or metal circular case Ais secured to the right-hand end of the wooden roller. The disk B is secured to the inside of said case, and together they revolve around the fixed pivot d, which passes through-central holes in the disk and the case and enters a hole in the end of the wooden roller 0. The pivot is made stationary by its square head m being placed in the bracket D, and secured by a screw, 01. One end of the spring E, (of blue steel, such as is used for watches and 'clocks,) is secured to the pivot d, close to and touching the inner surface of the-disk B. The other end of the spring passes through the aperture 1) made in the shoulder a of case A. (See Figs. (iand 5.) The edge of the disk 13, resting upon the shonlder a, referred to, and secured in that position by screws entering the holes ff, confines the spring in the space of the width of said shoulder a, between the disk B and the end of the case A. Thus one end of the spring 6' being secured to the stationary pivot and the other end to the case A, in which is secured the disk 13, and the said case being secured to the wooden roller, the untwisting pressure of the spring causes these parts and the roller to revolve when free to do so. The size and strength of the spring depend on the size and weight of the shade. The combination that stops the action of the spring is encircled by the flange of the disk B. (See Fig. 7.) The pin gis passed through an enlargement, (2, near the end of the pivot d, and is bifurcated at the point, into which bifurcation is inserted the lever h, which acts upon the barz' by the connecting wire rod 4. The bar z is also attached to the butt-end of the pin 9, and secured by a small pivot.

In the flange 7c are three slots or apertures at equidistance apart, one of which, Z, is shown, and into which a rounded projection or catch, i, formed upon the bar 2', drops and stops the action of the spring. Lowering the shade releases the catch (when'it is in working order) there being no resistance made by the lever h above; but the reverse pressure, caused by raising the shade, meets with resistance below, made by the butt-end of the fixed pin g,which presses the bar .6 more firmly against the side ICO it-0f releasing the catch, when pulling the shade will not do it. The key, Fig. 9, fits the head of the pivot d, and bywinding to the left will strengthen the spring.

The construction above described will provide a secure connection between the fixtures and the end ofthe roller, which latter may be perfectly solid, and largesized tacks may be employed at 0 to pass through the part a of the casing A, and through the part a of the flanged end piece, A, at the left-hand side of the roller. A pintle, (1', upon the bracket D, at the left-hand side of the roller 0, passes through the end of the flanged end piece, A, and supports the end of the roller.

I claim as my invention and desire to secure by Letters Patent-- 1. A spring-fixture for curtains, consisting of the casing A, the disk B, secured in said casing, and having a flange, 7c, provided with a slot or slots, Z, the shaft d, passed through said casing and disk, whereby such parts may turn on the shaft, the support g, connected with the shaft, the bar 2, connected to such support, and having a projection, i, to enter the slot Z, the lever 71, and the rod j, connecting the bar 1' with the lever h, substantially as and for the purposes specified.

2. The combination, in a curtain-fixture, of a casing adapted for connection with the curtain-roller, and having a flange or plate fixed rigidly to it and provided with a notch or notches, l, a spring for turning said case, a bar, 13, having a projection fitted to enter the notch or slot 1, a lever, h, a connection between said lever h and bar a, and non-rotating supports for said lever h and bar t, whereby the casing may be held against or subjected at will to the rotating action of the spring, substantially as and for the purposes specified.

3. The combination of the curtain-roller, the disk fixed with reference to said ro1ler,whereby a turning of the disk will effect a turning of the roller, a flange, It, provided on said disk, and having a slot or slots, Z, a shaft, (I, inserted through said disk and serving as an axis on which said disk may turn, a support, 9, a bar, t, pivoted to said support, and having a projection, i, to enter the slotl of flange k, the

lever h, and connection j, all substantially as and for the purposes specified.
